True North Restoration exists to restore the lives of our customers while serving the needs of our employees and communities with dedication and compassion.

"Efficient, fast, professional, and courteous. Initially I was going to use Rotor Rooter's recommended restoration until I realized they were trying to exploit the situation with up-selling and unnecessary work. True North gave an accurate and fair assessment and got the job completed."

"After heavy rain we had Groundworks mitigate water in our basement. They drafted a plan and advised on how to prevent water intruding on the east wall of our house, which consisted of a front and back bedroom. The water was currently only entering from the back bedroom, so Groundworks advised to put in an interior french drain and waterproofing. My wife and I specifically asked whether we should also mitigate the front bedroom, and they advised against because it would entail losing the bedroom closets, and the existing plan would mitigate water for the entire side of the house. We also specifically asked if we had water intrusion later in the front bedroom if it would be covered under the warranty and they confirmed that it would be covered. Now less than 2 years later, I have water in my front basement bedroom every time it rains. I have contacted the company repeatedly, and while they initially, verbally stated that they would correct the work and make things right, they have since claimed that the warranty only covers the back bedroom. They are now advising to do an additional assessment, and for me to pay for additional mitigation. In total, the sales tactics seem unethical, the customer service is atrocious, and I would never pay Groundworks to complete work on any project again. I strongly recommend everyone stay as far away from this company as possible."

FAQs for basement waterproofing projects in Denver, CO

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
